Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600972, here are decompositions:

13 + 8600959 = 8600972
31 + 8600941 = 8600972
73 + 8600899 = 8600972
229 + 8600743 = 8600972
271 + 8600701 = 8600972
379 + 8600593 = 8600972
439 + 8600533 = 8600972
463 + 8600509 = 8600972

Showing the first eight; more decompositions exist.
